The Data Organizer: A high traffic node for tracking detector data

The Data Organizer is part of a real-time tracker for hadronic collider experiments. It constitutes the tracker interface towards the Data Acquisition (DAQ): a high-speed data-traffic node, where thousands of words are received and simultaneously organized in an internal structured database, to be later promptly retrieved and delivered in response to specific requests. It is capable to process data at a rate of 40 MHz, thanks to the use of fast and very dense devices like IDT Supersync II FIFOs, Samsung fast SRAMs, and programmable logic from Xilinx XC9500XV and VIRTEX families. The programmability allows easy upgrade, evolution and fast reconfiguration to adapt the interface to different trigger and DAQ needs. The hardware-dedicated structure optimizes speed, size and cost.
